Im in the process of helping a buddy do an lq4 swap into his truck. The lq4 that we got came with drive be wire but we need it converted to a cable system. The guy that sold us the motor gave us a cable style TB. But never said anything about having to convert it. I searched the forums but came up with nothing. So do I have to buy a new harness and pcm or is there some way to convert it. Some help would be greatly appreciated.

Thanks

why dont you use the harness that was in the truck originaly?

 

Oops I guess I shoulda mentioned its a 68 GMC

 

that could be a tuff change over and may not even be posiable. someone around here might know how to do it.

do you plan on hotroding it at all? computer controled tranny?

 

Not trying to be a smart butt here but. Why not have someone like speartech make the harness and use a drive by wire pedal with an electronic trans? I personally think that would be sweet, I love a old school vehicle with 21st century tech in it.

 

Were gonna be doing a bit of modding but nothing overly extreme. I already have the 4l60e built and its done to the nuts so it will be there for a while. Might one day go back to a 400 or maybe even a 4l80. I thought about doing the electric pedal thing but I would have to buy the pedal setup and computer for it and a decent amount of time setting it up. So by the time thats all said and done I could probably find a new computer and harness for cheaper and it would be alot simpler.

You need a computer either way right?, just get a dbw one. I think it would be easier to just get a electronic pedal.

 

Personally, I don't like DBW...just and old school mental block I have. Would it be possible to bolt on the cable TB and use an 01-02 custom tuned truck PCM that's already set up for a cable? As far as the harness goes, I guess you could use and modify a truck harness, or check some of the companies that make retro-fit harnesses. Last I checked, Nelson Performance was offering engine swap harnesses...if the quality is anything like the efan harness I bought from him, I'm sure you'll be very happy with it.
